Chemical Name: Diisopropylamine
Synonyms: N-iso-Propyl-2-propanamine
Formula: C6H15N
CAS Number: 108-18-9
Appearance: Clear, colorless to pale yellow liquid, strong ammonia or fishy scent
Use Cases: Often found in organic synthesis, herbicide production, acid neutralization, specialty chemical manufacture
Precautionary Symbols: Corrosive, Flammable, Harmful
Main Dangers: High vapor pressure means fumes can catch fire quick; skin and eyes burn on contact; vapor irritates airway, causes coughing or burning; long vapor exposure possible nervous system impact; poorly ventilated rooms fill up with fumes fast
Signs of Overexposure: Eye redness, skin pain or blisters, nose and throat burning, dizziness, headache
Routes of Entry: Inhalation, skin, eyes, ingestion
Concentration: Usually above 99% pure when supplied
Main Ingredient: Diisopropylamine
Impurities: Trace amounts of other aliphatic amines possible if synthesized by crude or batch methods
Eye Contact: Rinse at gentle flow with water for at least 15 minutes, hold lids open, seek medical attention
Skin Contact: Remove contaminated clothing, flood skin under running water, soap up, medical help when irritation sticks around
Inhalation: Get out to fresh air, keep warm and at rest; if symptoms stay or worsen, get medical help
Ingestion: Do not try to force vomiting; rinse mouth, drink water if alert, then seek medical attention
Sensitivity: Flammable liquid, vapor forms explosive mixtures with air above 32°C
Suitable Extinguishers: Alcohol-resistant foam, dry chemical powder, CO₂ extinguishers
Fire Hazards: Vapors travel to sources of ignition, flashback possible; chemical decomposes into toxic gases like nitrogen oxides when burned
Protective Equipment for Responders: Full-body fire gear, self-contained breathing apparatus
Spill Response: Evacuate area, ban open flames, ventilate, wear gloves and chemical goggles
Containment: Absorb with sand, earth, or non-combustible material; never use sawdust
Cleanup: Shovel into suitable closed container, wash area with lots of water
Environmental Caution: Avoid runoff into drains or soil, prevents groundwater harm and fish kills
Safe Handling: Keep vape extraction high; tightly closed drum or bottle; avoid breathing vapor; never pipette by mouth; use grounding and bonding during transfer to stop static
Storage Conditions: Cool, dry, well-ventilated room; away from heat, sparks, and acids; segregate from oxidizers; avoid open containers
Personal Protective Gear: Chemical splash goggles, nitrile glove, face shield for splashes, lab coat
Engineering Controls: Fume hood or local exhaust to keep air clear
Exposure Limits: ACGIH TLV: 5 ppm (18 mg/m³) TWA; short-term exposures need extra caution
Respiratory Protection: Organic vapor respirators if exposure cannot be controlled with ventilation
Boiling Point: Around 84°C
Melting Point: -60°C
Solubility: Mixes easily with water, alcohol, and ether
Vapor Pressure: Relatively high at room temperature
Odor: Strong, fishy, ammonia-like
Density: About 0.72 g/cm³
Vapor Density: Heavier than air
Flash Point: 32°C (90°F) closed cup
Stability: Stays stable sealed, away from air and moisture
Reactive With: Strong oxidizers, acids, acid anhydrides
Dangerous Products: Burns to make toxic nitrogen oxides and carbon monoxide; mix with acids or oxidizers can give off heat and gas, which sometimes triggers fire or explosion
Acute Toxicity: Can irritate or burn skin, eyes, lungs; ingestion upsets gut, can burn mouth and throat
Chronic Exposure: Prolonged exposure raises risks: respiratory distress, asthma, persistent dermatitis
LD50 (Oral, rat): About 820 mg/kg
Carcinogenicity: Not classified as carcinogen by IARC or US agencies
Sensitization: Possible but rare for allergy-type response
Aquatic Toxicity: Harmful to fish and aquatic invertebrates at high concentrations
Soil Mobility: Moves quickly through soil; runoff can contaminate water table
Persistence: Biodegrades under aerobic condition after escaping into environment, but concentrated spills linger
Bioaccumulation: Unlikely to build up in living tissue
Safe Disposal: Collect waste in tight, labeled drum; never tip down drain or throw in regular trash
Preferred Methods: Incineration by licensed waste handler
Contaminated Packaging: Triple-rinse, let them air out, then send for hazardous waste disposal
Shipping Class: Flammable liquid, regulated on road, rail, air, and sea
Packing Group: II (medium danger)
UN Number: 1158
Label Required: Flammable liquid, corrosive warning
OSHA Regulations: Diisopropylamine included in workplace hazardous chemical standards
EPA Regulations: Reportable Quantity (RQ) for environmental release applies; subject to hazardous substance list
Community Right-to-Know: Enforced as hazardous chemical in both federal and state plans
Worker Training: Mandatory for storage, handling, and emergency steps by governing labor agencies
